Acknowledgments

I would like to thank all the folks at Sybex who made this a most enjoyable and rewarding
experience, including Erica Yee and Jeff Kellum, who reinforced my attention to detail.
Thanks go to Biju for not letting me write too many of these chapters myself (again). Thanks
also to Kim Wimpsett, who filled in the gaps from my college writing courses, and to Joe
Johnson and Bob Wahl for their insightful comments and suggestions.
This book wouldn’t be possible without the love and support from my family throughout the
long nights and weekends when I still managed to find time to give the kids a bath and read
books before bedtime. I loved every minute of it.
Thanks also to my professional colleagues, both past and present, who provided me with
inspiration, support, and guidance and who pushed me a little further to take a little risk now
and then, starting with that math teacher in high school, whose name eludes me at the moment,
who introduced me to computers on a DEC PDP-8 with a teletype and a paper tape reader.



Bob Bryla
I would like to thank the wonderful people at Sybex for their high-quality work. Thank you,
Jeff (development editor), for supporting me, making valuable comments, and ensuring the
chapters have the smooth flow and transition. I thank Erica Yee (production editor) for making
sure every piece of the book ties together. I thank each one of the professionals at Sybex involved
in the publication of this book for their hard work.
I thank Kim Wimpsett (copy editor) for her patience with my writing. Thank you, Kim; your

edits removed the confusion from several sentences and made a difference to the chapters. I
thank Joe Johnson and Bob Wahl for their technical review and invaluable comments. Bob (Bryla),
thank you for doing the initial study and laying the groundwork for the book.
I owe for the support and encouragement from my colleagues at work. Thank you, Paul,
Wendy, Charles, and Balbir.
Finally, all of this was possible because of the love and support from my beloved wife, Shiji.
Thank you, Shiji, for occupying Joshua while I sat in front of the computer. Thank you, Joshua,
for leaving me alone and playing with “Thomas” when I said that “Appa is working.”

Introduction

The information technology (IT) industry has high demand for professionals, and Oracle cer-
tifications are the hottest credential in the database world. You have made the right decision to
pursue an upgrade to your certification, because keeping your Oracle certification current will
give you a distinct advantage in this highly competitive market.
Most readers should already be familiar with Oracle and do not need an introduction to the
Oracle database world. For those who aren’t familiar with the company, Oracle, founded in
1977, sold the first commercial relational database and is now the world’s leading database
company and second-largest independent software company, with revenues of more than $10
billion, serving more than 145 countries.
Oracle databases are the de



facto standard for large Internet sites, and Oracle advertisers
are boastful but honest when they proclaim that “the Internet runs on Oracle.” Almost all big
Internet sites run Oracle databases. Oracle’s penetration of the database market runs deep
and is not limited to dot-com implementations. Enterprise resource planning (ERP) applica-
tion suites, data warehouses, and custom applications at many companies rely on Oracle. The
demand for database administrator (DBA) resources remains higher than others during weak
economic times.
This book is intended to help you upgrade from an Oracle 9

i

Certified Professional to an
Oracle 10

g

Certified Professional (OCP), clearing the way to pursue an Oracle Certified Master
(OCM) certification. Using this book and a practice database, you can learn the new features
of the Oracle 10

g

Database (Oracle 10

g

) and pass the 1Z0-040 Oracle Database 10

g

: New Fea-
tures for Administrators exam.

Why Become an Oracle Certified Professional?

The number-one reason to become an OCP or maintain an OCP certification is to gain more vis-
ibility and greater access to the industry’s most challenging opportunities. Oracle certification
is the best way to demonstrate your knowledge and skills in Oracle database systems.
Certification is proof of your knowledge and shows that you have the skills required to sup-
port Oracle core products. The Oracle certification program can help a company identify

proven performers who have demonstrated their skills and who can support the company’s
investment in Oracle technology. It demonstrates that you have a solid understanding of your
job role and the Oracle products used in that role.
OCPs are among the best paid in the IT industry. Salary surveys consistently show the OCP
certification to yield higher salaries than other certifications, including Microsoft, Novell, and
Cisco.
So, if you have an Oracle 9

i

OCP certification, you have a solid practical background as a
DBA, and you’re ready to upgrade your certification to Oracle 10

g

, this book is for you!

Introduction

Oracle Certifications

Oracle certifications follow a track that is oriented toward a job role. The certifications consist
of database administration, application developer, and web application server administrator
tracks. Within each track, Oracle has a multitiered certification program.

In addition to this multitiered approach, Oracle provides upgrade paths from previous ver-
sions of Oracle as well as special accreditations that you can attach to your certification.
The material in this book will address only the upgrade from the Oracle 9

i

to the Oracle 10

g


database administration track and the exam 1Z0-040 Oracle Database 10

g

: New Features for
Administrators. Other Sybex books at



can help students new to the
DBA world prepare for the OCA exam 1Z0-042 Oracle Database 10

g

: Administration I and for
the OCP exam 1Z0-043 Oracle Database 10

g

: Administration II.

See the Oracle website at

/>

for the latest information on all of Oracle’s certification paths along with Oracle’s

training resources.

The role of the DBA has become a key to success in today’s highly complex database systems.
The best DBAs work behind the scenes but are in the spotlight when critical issues arise. They
plan, create, maintain, and ensure that the database is available for the business. They are
always watching the database for performance issues and to prevent unscheduled downtime.
The DBA’s job requires broad understanding of the architecture of Oracle database and requires
expertise in solving problems.
Since this book focuses on the DBA track, the following sections present a closer look at the
different tiers of this track.

Oracle Database 10

g

Administrator Certified Associate

The Oracle 10

g

Administrator Certified Associate certification is a streamlined, entry-level

certification for the database administration track and is required to advance toward the more
senior certification tiers. This certification requires you pass the following exam that demon-
strates your knowledge of Oracle basics:


1Z0-042 Oracle Database 10

g

: Administration I

Oracle Database 10

g

Administrator Certified Professional

The OCP tier of the database administration track challenges you to demonstrate your continu-
ing experience and knowledge of Oracle technologies. The Oracle 10

g

Administrator Certified
Professional certification requires achievement of the Administrator Certified Associate certifi-
cation, as well as passing the following exam:


1Z0-043 Oracle Database 10

g

: Administration II

Introduction

xvii

In addition, the OCP candidate must take one instructor-led in-class course from the follow-
ing list:


Oracle Database 10

g

: Administration Workshop I


Oracle Database 10

g

: Administration Workshop II


Oracle Database 10

g

: Introduction to SQL


Oracle Database 10

g

: New Features for Administrators


Oracle Database 10

g

: Program with PL/SQL
If you already have your OCP 9

i

or earlier and have elected to take the upgrade path, you
do not need to take a class to achieve your OCP for Oracle 10

g

.

You should verify this list against the Oracle education website (

www.oracle

.com/education

), as this list may change without any notice.

Oracle Database 10g Certified Master

Oracle Database 10

g

Administration Certified Master is the highest level of certification
that Oracle offers. To become a certified master, you must first achieve Certified Professional
status, then complete two advanced instructor-led classes at an Oracle education facility, and
finally pass a hands-on, two-day exam at Oracle Education. The classes and practicum exam are
offered only at an Oracle education facility and may require travel.

More details on the required coursework will be available in late 2004.

Oracle 10

g

Upgrade Paths

Existing OCPs can upgrade their certification in a number of ways: A single exam can upgrade
an Oracle 8

i

DBA directly to Oracle Database 10

g

certification in addition to the certification
upgrade from Oracle 9

i

to Oracle Database 10

g

covered in this book. Also, Oracle 7.3 and Ora-
cle 8 DBAs can upgrade to an Oracle 9

i

certification with a single exam.

Oracle Database 10

g

Administrator Special Accreditations

New to the Oracle certification program are the Oracle Database 10g Administrator Special
Accreditation programs. These accreditations formally recognize the specialized knowledge of

OCPs, in particular database administration areas such as high availability, security, and 10

g


Grid Control. OCPs who pass one of these special accreditation exams will receive a certificate
that formally recognizes their specialized competency. The first Oracle Database 10g Special
Accreditation will be the High Availability Special Accreditation, available in 2004.

Tips for Taking the OCP Exam

Use the following tips to help you prepare for and pass the exam:


The OCP upgrade exam contains about 55–80 questions to be completed in 90 minutes.
Answer the questions you know first so that you do not run out of time.


Many questions on the exam have answer choices that at first glance look identical. Read
the questions carefully. Do not just jump to conclusions. Make sure you clearly understand

what each question asks.


Some questions are based on scenarios. Some of the scenarios contain nonessential informa-
tion and exhibits. You need to be able to identify what’s important and what’s not important.


Do not leave any questions unanswered. There is no negative scoring; always answer a
question rather than leave it blank. After selecting an answer, you can mark a difficult ques-
tion or one that you’re unsure of and come back to it later.


When answering questions you are not sure about, use a process of elimination to get rid
of the obviously incorrect answers first. Doing this greatly improves your odds if you need
to make an educated guess.

If you are not sure of your answer, mark it for review and then look for other questions that
may help you eliminate any incorrect answers. At the end of the test, you can review the
questions you marked earlier.
You should be familiar with the exam objectives, which are included in the
front of this book as a perforated tear-out card. You can also find them at
www.oracle.com/education/certification/objectives/index.html?40.html.
